Diving in the Seychelles in May

Conditions in May

May marks one of the sweet spots for diving in Seychelles, offering a delightful transition from the northwest monsoon to the southeast trade winds. This interim period brings some of the best conditions you'll experience all year. You're looking at generally calm seas, with minimal chop, making for wonderfully comfortable boat rides to the dive sites. The surface is often glassy, reflecting the clear blue skies above, a perfect prelude to what awaits beneath the waves. It’s truly a time when the Seychelles lives up to its paradisiacal reputation, both above and below the waterline.

Water temperatures in May are consistently warm and inviting, typically hovering around 28-29°C (82-84°F). This means you’ll be super comfortable, even during longer dives. Visibility is exceptional during this transitional month, often soaring to an impressive 25-30 meters, sometimes even more. Imagine seeing that far through crystal-clear water; it’s an absolute dream for photographers and anyone who just loves to take in the sheer beauty of the reef. Currents during May are generally mild to moderate. On some outer sites, especially around the Amirantes or Farquhar groups, you might encounter stronger drifts, but these are often predictable and add to the thrill of a drift dive, bringing in those larger pelagic species. Close to the inner islands, currents are often negligible, perfect for relaxed exploration.

What you will see

May in Seychelles is an amazing time for marine life encounters, thanks to the fantastic visibility and comfortable water conditions. This period is particularly good for pelagic sightings, as the clear waters attract larger fish to the outer reefs. You have a great chance of encountering grey reef sharks, blacktip reef sharks, and even the occasional silky shark gliding by. Eagle rays are a common and graceful sight, often seen cruising in groups over the vibrant coral gardens. Keep your eyes peeled for barracuda schools, often swirling in impressive tornadoes, especially on pinnacles and submerged reefs. The clear water also enhances your chances of spotting tuna and other schooling fish in the blue.

While mantas are more common during specific plankton blooms sometimes associated with the monsoons, May can still offer delightful encounters, particularly around the outer atolls where nutrient-rich upwellings can occur. The calm conditions are also ideal for observing green and hawksbill turtles, which are abundant throughout the Seychelles. You'll often see them feeding placidly on sponges or cruising majestically past. For macro lovers, the reefs are teeming with life. Look closely and you'll discover a world of nudibranchs, colorful reef fish like angelfish and butterflyfish, and various crustaceans nestled amongst the corals. The vibrant coral gardens themselves are a spectacle, showing off their full splendor in the excellent visibility.

Top dive sites this month

For May diving, focus on the inner islands and some of the more accessible outer island groups. Three fantastic sites come to mind for this period. Firstly, Shark Bank, located off Mahé, is a perennial favorite and truly comes alive with amazing visibility in May. Here, you'll almost certainly encounter several species of reef sharks, massive schools of snapper and barracuda, and often eagle rays. The granite boulders create interesting topography, and the mild currents typically present in May make it a comfortable yet thrilling dive. Secondly, the Ennerdale Wreck, also near Mahé, is another superb option. This 1970s oil tanker sank due to an explosion and now lies in two main pieces. In May's clear water, you can fully appreciate its immense structure and the prolific marine life that has colonized it, including giant groupers, snapper, and sometimes even a whale shark passing by.

Further afield, if your liveaboard ventures to the gorgeous Amirantes group, Poivre Atoll offers breathtaking diving. The coral reefs here are pristine, and the clear May waters are perfect for exploring its diverse topography, from shallow coral gardens to dramatic drop-offs. Expect to see large numbers of reef sharks, rays, and huge schools of pelagic fish. These sites offer a diverse range of experiences, from wreck diving to vibrant reef exploration, all enhanced by the superb conditions May typically brings to the Seychelles archipelago.

Practical tips for your trip

Given the warm water temperatures of 28-29°C (82-84°F) in May, a 3mm shorty or full wetsuit is more than sufficient for most divers. Some seasoned warm-water divers might even be comfortable in just board shorts and a rash guard, but a thin wetsuit offers protection from accidental bumps and mild stinging organisms. This month is fantastic for all levels of divers. Beginners will appreciate the generally calm seas and excellent visibility for their first underwater explorations, while advanced divers can revel in the pristine conditions for deeper, more adventurous dives and optimal photography opportunities. The mild currents around the inner islands make for relaxed experiences, while outer sites offer exhilarating drift diving for the experienced.

Liveaboard availability in May can be quite good, as it's not yet peak season for the southeast trade winds when many choose to visit the outer islands. Booking in advance is always recommended, especially for popular itineraries, to secure your preferred boat and cabin. Pack light, breathable clothing, plenty of reef-safe sunscreen, a wide-brimmed hat, and insect repellent for evenings on deck or island excursions. Remember that while May generally offers great weather, tropical climes can be unpredictable, so a light rain jacket isn't a bad idea, just in case. Enjoy the incredible underwater world of Seychelles; May is truly one of its finest months!
